A frequency generator (a device that produces sinusoidal signals whose frequency and amplitude can be independently set) is used to power a horn. The frequency is set to 2000Hz, and for a particular amplitude the sound intensity is measured to be 0.050 W/m2 at a distance of 12m.

What is the power output of the horn?

What is the intensity of the sound wave 2m from the horn?

Taking the speed of sound in air to be 334m/s, what is the wavelength of this sound?
